No More Watermarks !

The final stage of any good car wash system is a pure water rinse that ensures a spot free finish. Now, thanks to the Aqua Gleam in-line filter you can enjoy the benefits of virtually pure water, giving you a spot free finish when washing your car at home.

Features & Benefits:

  • Eliminates watermarks & streaks
  • Virtually pure de-ionised water
  • No need to chamois dry
  • Significantly enhanced shine
  • Supplied with two quick connect hose end fittings
  • Many other applications - motorcycles, boats, aircraft, motorhomes, etc

Purifies ordinary tap water to 30 parts per million (30ppm). Water at this level of purity will provide good spot free results, making light work of the washing process. In areas with particularly hard water it may be preferable to use a 30ppm filter rather than the 0ppm filter in order to prolong filter life.


  • Length - 350mm (13.7")
  • Width - 100mm (4") W

It is not recommended to use the Aqua Gleam filter in conjunction with a pressure washer (above 100psi). Connect to the hose for the final rinse.

Oh my goodness

I was sceptical to be honest . . But bloody hell! I couldn't believe it, what a transformation! No spots, no streaks . . Nothing! Try it for yourself and sit back enjoy . . 😊

Same as others have said, I live in a hard water area, you can use this on a waxed car to give a quick wash and then towel dry to remove pollen & dust on a car. Connect up rinse the car. the best bit is seeing the normal tap water coming through the hose then change to deionised water that sheets off a waxed car, then either leave to dry or towel off. Just wished you could change the granules rather than the whole cartridge.

Rinse and leave

This is unreal. I washed my black Jag and my mates black C63 in the sun and rinsed with the Aqua Gleam filter, left them to dry and not a mark in sight. It's amazing and leaves a streak free shine. Love it.

brilliant finish

I have always hated the water marks left when cleaning a black car, those days are over, don't use a quick detailer anymore, just Gtechniq uv wash, final rinse with the Aqua Gleam and the dry it off with Swissvax waffle towel, the best finish I've had from a 30 minute wash..

I didn't believe it, now I do!

This is an amazing product that I have no hesitation in recommending. I live in a hard water area, so white streaks are common place unless you shammy and shine to avoid them. The Aqua Gleam avoids that altogether, you simply apply with a hose at the end of your wash and hey-presto, no streaks. Brilliant!!!

Watch it Vanish!

Unbelievable – Wash, rinse and watch the water disappear leaving absolutely nothing. Yes, it really does work. I was somewhat sceptical at first as this is not a cheap product but if you have a car you want to keep as ‘swirl’ free as possible this really does work leaving no watermarks on the car and actually seems to leave an extra sparkle. I’m about to by my 4th so it must be good.

No streaks, just shine

Isn't it nice when something lives up to its claims - this really does leave a lovely shine without streaks if you are in a rush. If you have time then using this as part of your car cleaning regime produces even better results!
